Abstract
Abstract The digold(I) complex [Au 2 Cl 2 (Cy 2 PCH 2 PCy 2 )] reacts with 4,4′‐diphenylene diboronic acid to form a triangular macrocyclic complex with twisted Au‐P‐C‐P‐Au groups at the three corners. The synthesis of the complex and its chemical oxidation produced [6]cycloparaphenylene ([6]CPP) in 59 % overall yield.
